 * Revision 1.7  2006-12-26 10:25:37  ppiqueras

 * Corregidas las dependencias con las nuevas ubicaciones de clases: IXMLType, XMLElement, IXMLComplexType, etc. (en libRemoteServices)

 *

 * Revision 1.6  2006/12/26 09:27:26  ppiqueras

 * Cambiado "atttibutes" en todas las aparaciones en atributos, m?todos, clases, paquetes o comentarios por "fields". (S?lo a aquellas que afectan a clases dentro del proyecto extWFS2).

 *

 * Revision 1.4  2006/10/11 11:19:58  jorpiell

 * Una nullPointerException que no se comprobaba

 *

 * Revision 1.3  2006/10/10 12:55:06  jorpiell

 * Se ha a?adido el soporte de features complejas

 *

 * Revision 1.2  2006/10/02 09:09:45  jorpiell

 * Cambios del 10 copiados al head

 *

 * Revision 1.1.2.1  2006/09/19 12:28:32  jorpiell

 * Ya no se depende de geotools

 *

 * Revision 1.1  2006/09/18 12:07:31  jorpiell

 * Se ha sustituido geotools por el driver de remoteservices

 *

 * Revision 1.1  2006/07/24 07:30:33  jorpiell

 * Se han eliminado las partes duplicadas y se est? usando el parser de GML de FMAP.

 *

 * Revision 1.5  2006/06/21 12:35:45  jorpiell

 * Se ha a?adido la ventana de propiedades. Esto implica a?adir listeners por todos los paneles. Adem?s no se muestra la geomatr?a en la lista de atributos y se muestran ?nicamnete los que se van a descargar

 *

 * Revision 1.4  2006/06/14 07:57:19  jorpiell

 * Ya no se usa la estrategia ni se usa geotools para hacer el getFeature. Ahora se usa ?nicamente para el parseo de GML

 *

 * Revision 1.3  2006/05/25 15:32:01  jorpiell

 * Se ha a?adido la funcionalidad para eliminar el namespace de los tipos de atributos

 *

 * Revision 1.2  2006/05/25 10:32:21  jorpiell

 * Se ha renombrado la clase WFSFields por WFSAttributes porque era algo confusa

 *

 * Revision 1.1  2006/05/23 08:07:00  jorpiell

 * A?adido un m?todo para detectar el tipo de geometr?a
